EUGENE U. GIBBS, OF MOUNT HOLLY, NEW JERSEY, ASSIGNOR TO THE GIABBSBOILER COMPANY, OF NEW JERSEY.

STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 552,362, dated December31, 1895.

Application filed May 2, 1895. Serial No. 547,852. (No model.)

T all whom it may concern:

Be it known that I, EUGENE U. GIBBs, a citizen of the United States,residing at Mount Holly, in the county of Burlington,in the State of NewJersey, have invented a new and useful Improvement in Steam-Boilers,which improvement is fully set forth in the following speciiication andaccompanying drawings.

My invention relates to steam-boilers; and

1o it consists of novel attachments therefor,

which are adapted to be placed within the firebox of the boiler, therebygreatly increasing the evaporating capacity of the same, the circulationand the amount of heating-surface x5 being also greatly augmented.

It further consists of a novel construction of the above attachment bymeans of which greater heating-surface and increased circulation areobtained.

It further consists of novel details of construction, all as will behereinafter set forth.

Figure l represents a vertical section of a steam-boiler embodying myinvention, a portion of the same being in elevation. Fig. 2 represents asection on line Fig. 1. Fig.

3 represents, on an enlarged scale, a perspective view of a novelconstruction of auxiliary attachment employed. Fig. 4 represents abottom plan view of the attachment seen in 3o Fig. 3.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates a boiler, the same beingprovided with an in- 3 5 closing casing B, the fire-door C, and thecombustion-chamberD, said boiler being also provided with a grate andash-pit, and other appurtenances of the usual construction.

E and F designate the upper and lower tube-v 4o sheets, in which thefire-tubes G are secured.v

H designates an auxiliary attachment or water-heating chamber, severalof which are secured in the upper portion of the fire-box orcombustion-chamberD,the construction of which chambers will bebestunderstood from Fig. 3, the same consisting of the central header Jand the headers K and L, at either side thereof, a communication beinghad between each of saidlheaders.

M, N, and P designate the bottom headers, which are arranged under therespective headers K, J, and L, and are connected thereto by means ofthe water-tubes Q, R, and S, it being understood that said lower headersalso communicate with each other at a point Y near their extremities,and that the central headers J and N are in the present instance longerthan the adjacent headers on either side.

T designates a nozzle or nipple, having a closed top,which is attachedin the present instance to the central header J, and is provided with aslot U therein, through which the water and steam are discharged intothe boiler above the tube-sheet F.

V designates an opening in the lower header N, near the extremitythereof, by means of which communication is had with the interior of theboiler through the pipe W, which leads into the water-leg X,whichsurrounds the iirebox, as will be understood from Fig. l.

It will be noticed in the present instance l have shown the centralheaders J and N connected by four tubes, while the outer headers K L andM P, respectively, are connected by three tubes; but it will of coursebe apparent that the number of said headers and tubes may be variedaccording to requirements, and it will further be apparent that thenumber of said attachments or water-holding chambers H (shown-in Fig.3)which are to be secured within the chamber D may be also increased ordiminished, according to requirements, and the manner of attachmenttothe tube-sheet F and to the side of the fire-box or water-leg may alsobe varied, so as to still come within the scope of my invention.

The operation is as follows: The connection having been made between thewater-leg of the boiler and the bottom of the chamber H, preferably atthe point V, by means of the pipe W, it will be seen that as the waterin said attachment H is subdivided into a number of small streams whichiow through the pipes Q, R, and S the same will be heated very quicklyand will thus cause a rapid upward circulation, the water beingdischarged through the outlet U of each chamber H, the colder and moresluggish water in the water-leg X being thus caused to circulaterapidly, being withdrawn at practically every point around the lire anddischarged upwardly through `the crown-sheet, a boiler lof greatevaporative ca- IOO pacity and having a very rapid circulation beingthus produced.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A boiler having a water leg, upper and lower tube sheets, luestherebetween, and a series of water holding chambers located in the iirebox of said boiler, said chambers consisting of the headers, K, J, L,and M, N, P, water tubes therebetween, a nipple extending upwardly fromone of said headers, and closed at its top and having a slot in itssides, said nipple being extended through an adjacent tube sheet, one ofthe lowerheaders being provided with an opening, in combination with aconduit leading therefrom, to the interior of the boiler, substantiallyas described.

EZ. The herein described attachment or water chamber consisting of theheaders K, J, L, and M, N, P, water tubes therebetween, a nipple leadingfrom said header J at above its central point, closed at its top, andhaving a slot in its sides, and an opening in the lower central headerat one side of its center, substantially as described.

rlhe herein described attachment or wa ter ,holder chamber, consistingof the header J, having a centrally located nipple, with a closed top,and slots in its sides, the adjacent headers K and L, the lower headerslll, N, and P, the water tubes intermediate the above headers, the inletV removed to one side, and the communication between said lower headersadjacent said inlet V, substantially as described.

el. A boiler having a water leg, upper and lower tube sheets, iluestherebetween and a series of water holding chambers located within theiire box of said boiler, consisting of the header J having the centrallylocated nipple with a closed top, and a slot in its sides, said nippleextending through the adjacent tube sheet, the headers K and L adjacentsaid header J, the lower headers M, N, and P, water tubes intermediatesaid headers, the inlet V removed to one side, and a communicationbetween said lower headers, adjacent said inlet V, in combination with aconduit leading from the latter to the water leg or interior of theboiler, substantially as described.
